IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 41, E98, dated January 12, 1864.

To aZZ whom it may concern.-

Be it known that I, CHARLES CROZAT (JoN- VERSE, ofDubuque, in the county of Dubuque and State of Iowa, have invented a new and useful Baking and Cleaning Attachment for the Grates of Stoves, Furnaces, &c.; and I do hereby declare thatthe following is afnll, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a vertical central section of a grate with my invention applied to it; Fig. 2, a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the two figures.

This invention consists in the employment or use of a swinging toothed grate placed underneath the grate proper of the stove or furnace, and so arranged in relation therewith that the toothed grate, when not in use, may be sufiiciently far below the grate proper as to allow a free passage of air to the tire, and also allow ashes and cinder-s to escape casually through said grate proper, the toothed grate at the same time being capable of being raised when necessary to rake the tire to admit of the escape of ashes therefrom, and also clean the grate proper of cinders or clinkers which may be wedged or caughtbetween its bars.

To enable those skilled in the art to fully understand and construct my invention, 1 will proceed to describe it.

A represents the grate of a stove, which may be of circular or other form to correspond with the form of the stove, and constructed in the usual way of parallel bars at a suitable distance apart to admit of a free passage of air through it and the escape of ashes from the fire chamber above it. The grate is fitted in the bottom of the fire chambar by means of journals a a at its back part, to admit of it being lowered or dropped down into the ash-box B when it is necessary to clean out the stove, and the grate, when in use, may be sustained at its front part by any suitable catch, 0.

Within the ash box B, and directly underneath the grate A, there is a similar grate, D, thebars of which are provided with teeth I), projecting upward a suitable distance, and of such a width that they may pass freely between the bars of the grate A. The back part of the grate D is provided with a pendent bar, 0, the lower end of which is connected by a hinge orjoint, d, to the back part of the ash box B, as shown clearly in Fig. 1. The front part of the grate D has a rod, E, attached to it by a joint or hook connection, and said bar passes loosely through the bottom of the ash-box, and is connected at its lower end to a lever or treadle, F, which has its fulcrum at 6. When the toothed grate D is not in use. it has an inclined position in the ash-box, as shown in red in Fig. 1, so as not to interfere in the least with the free passage of air into the fire-chamber through the grate proper, A, nor interfere with the casual est-ape of ashes therefrom. This inclined position of the toothed grate D is due to its gravity only. When the grate proper, A, becomes choked with cinders or clinkers, or when the fire requires taking, the operator simply depresses the outer part of the lever or treadle F with his foot, and thereby throws up the toothed grate D, the teeth I) of which are forced between the bars of the grate proper, A, effectually cleaning the spaces between the same. and also serving as a rake to deprive the fire of ashes. The toothed grate D is shown in an elevated position in black outline in Fig. 1, and it may be elevated repeatedly until the grate A is thoroughly cleansed or the tire raked.

This invention, it will be seen, obviates the necessity ofa movable or shaking grate proper, such as is generally used to deprive the fire of ashes, and it forms a far more convenient means for etfectin g such result in consequence of being operated by the foot, and also possesses the advantage of keeping the grate proper free from cinders or clinkers, which might otherwise choke or clog it, and which cannot be removed by the shaking of an ordinary shaking grate.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The arrangement of the toothed grate D, rod E, and treadle F with the hinged grate A and stoy'e-bottom B, in the manner and for the purpose herein shown and described.
